Figure 3. GLS and Fitness are correlated with DMN CBF.
Scatterplots show relationships between DMN CBF and each health metric. Cardiorespiratory fitness (fitnessCR) showed a positive relationship with DMN CBF (A) and GLS showed a positive relationship with DMN CBF (B). Note: To render GLS-CBF relationships more interpretable, participant's GLS values were converted such that higher scores now reflected superior myocardial shortening mechanics (by multiplying each participant's score by −1).
